Thermal Dispersion
& Paddle Type Flow Switch
visit our website
1
OPERATING PRINCIPLEThermal dispersion flow switches measure the
velocity of a liquid inside a pipe or channel.
The switch’s probe contains two key components
– a heating sensor and temperature sensor. The
heating sensor is positioned closest to the flowing
liquid and provides a consistent heat. The
temperature sensor measures the temperature
emitted from the heating sensor.
When liquid is flowing, there is a temperature
difference between the two sensors. The
temperature difference has an inverse relationship
with the flow velocity (fast flowing liquids will result
in greater heat differences and vice versa).
Since the device contains no moving parts, has no
wear and tear and maintains a long lifespan.
High sensitivity and accuracy.
Suitable for corrosive and hazardous
conditions.
Able to be calibrated for liquids with different
densities and impurities.
Suitable for complex locations with easy
installation.
Customized probe lengths available.
Three different output signals options.
FEATURES APPLICATIONPetrochemicals, Hydroelectric plants, Shipyard,
HVAC Systems, Steel Industry Food and Beverage,
Pharmaceutical,Optics and Semiconductor Industry,
Cooling pipes flow control
Any pipes carrying liquid where flow measurement
is needed.

1. Use the water-proof gasket provided 2. The distance "a" should be 4 times larger
than the switches’ screw diameter. (Fig. 1)3. The pipe is bubble free for proper
functioning. (Fig. 2)4. For not-completely-filled pipes, install from
the bottom. The liquid level needs to be higher than the probe height. (Fig. 3)

Flow Switch can detect liquid movement in pipes. When the liquid is static or nonexistent, the spring is fully extended pulling the magnet downward and opening the switch.As flow occurs and the paddle is thrusted forward 20BC~30 C (or more) the paddle will push the magnet upward and actuate the switch (closing the circuit) The length of paddle can be adjusted to the pipe's diameter.

PRINCIPLE
1. The paddle length is dependent on the lowest paddle point to actuate the switch. Cut the pad-dle at appropriate pipe size mark or wherever desired. The minimum is 1".
2. The paddle must be at a right angle to the direc-tion of flow
3. The FLOW mark on the screw must beparallel to the pipe.
4. Before installing the unit to a tee pipe, apply thread seal tape to the screw and then tighten.
1. The pressure and temperature ranges as shown in the catalog, must not be exceeded and also take the abrupt pressure and temperature into consid-erations.
2. Large sudden changes in liquid temperature and density (specific gravity) changes will influence the flow switch accuracy
3. Although highly rigid and durable, shock and vibra-tion should be minimized.
4. Excessive fluid debris might inhibit paddle opera-tion. Occasionally remove switch and clean off any debris.
5. Sealing electrical connections and the connection will reduce moisture damage.
1 Not recommended for 1" or smaller NPT plastic pipes.
